Diamond Color, Clarity, Carat And Anatomy Charts

Most diamonds appear colorless but actually have slight tones of yellow or brown. The closer the stone comes to colorless, the more valuable it is. Diamonds are graded on a color scale ranging from D (colorless) to Z (heavily tinted.)

The pavilion angle of 40.8 degrees is great, it should produce a high volume of light return! The crown angle of 35.5 degrees is just a hint steeper than my preferred range of 34.3 – 35.0 degrees. The GIA rounds this measurement off to the nearest half a degrees, and my suspicion is that the crown angle is actually a bit steeper than 35.5 degrees, since the crown height is 16.5% and this is likely to cause the diamond to display a bit more dispersion (colored sparkle / fire) as opposed to a virtual balance of brilliance (white sparkle) and dispersion. However this effect will be tempered a bit by the fact that the diamond has 75% lower girdle facets, which tend to create sparkle which is larger in size.

In addition, the crown angle is a bit shallow at 33.5 degrees, as is the 14% crown height, thus the diamond is likely to exhibit a higher volume of brilliance than dispersion, or a virtual balance of dispersion; this effect is likely to be heightened by the 80% lower girdle facet length, which tends to produce smaller flashes of light / sparkle; and this is an issue because our eyes can experience difficulty dispersing smaller flashes of light into colored light / fire, and thus this diamond is probably quite brilliant, but not very fiery; of course there is always the possibility that you prefer diamonds that exhibit smaller pin-fire type sparkle, and more brilliance, as opposed to diamonds that exhibit larger, bolder flashes of light, and a virtual balance of brilliance and dispersion.
